Review on Gizhome 1 Inch Swivel Bearing Trolley by Rod Evans

I bought these to screw to the bottom of a small stand that holds a large metal dog food container. Now I can more easily roll the jar out of the cupboard to feed the dogs (instead of having to put the jar on the floor or pick it up). The included mounting screws are welcome, but a little underpowered for heavier plywood/softwood/pine loads. Also, the diameter of the wheels is small (as expected/described) which means they don't roll very well on seams in stone tiles and certainly won't roll over something like a door jam. Ideal for smooth surfaces but consider use/application before ordering. Happy with what I got for the price.
